本文叙述的是当入射波基本上是平面波且为线极化时,对介质平板、空心介质楔及空心介质园锥附近之微波场的测量。这些测量是作为对介质物体的散射进行射线追踪说明的部分工作而完成的。本文给出了导波沿介质平板、两块平板构成的空心介质楔及空心介质园锥传播的证据。测量时使用一台微波干涉仪。速调管产生的微波频率为9.4.00GC/Sec。测试设备采用普通的连接方法,其方框图表示在图1中。测量精度,在功率方面为±0.3db,在相位方面为±2°。发射天线和接收天线之间的距离足够远,以至于超过了远区场的标准2D~2/λ。
This paper describes the measurement of the microwave field near the dielectric slab, the hollow dielectric wedges and the hollow conic cone when the incident wave is essentially a plane wave and linearly polarized. These measurements were done as part of the job of ray tracing of the scattering of a medium object. In this paper, the evidence of the propagating wave propagating along the dielectric slab, the hollow medium wedge consisting of two slabs and the hollow medium conic is given. A microwave interferometer is used for the measurement. The klystron produces a microwave frequency of 9.4.00GC / Sec. The test equipment uses an ordinary connection method, the block diagram of which is shown in FIG. 1. Measurement accuracy of ± 0.3db in terms of power and ± 2 ° in phase. The distance between the transmitting antenna and the receiving antenna is far enough that it exceeds the standard 2D ~ 2 / λ of the far field.
